Knowra Deciduous tree Deciduous tree A deciduous tree sheds its leaves during a recurring season, commonly in response to cold or dry conditions. Leaf loss reduces water loss and helps the tree survive unfavorable growing conditions.
Abscission : The regulated separation of a plant part, such as a leaf, from the rest of the plant. A layer of specialized cells forms at each leaf base before seasonal leaves detach.
Leaf : A plant organ specialized for light capture, gas exchange, and often photosynthesis. Deciduous trees periodically shed this principal photosynthetic organ.
Agroforestry : Land-use systems that combine trees with crops, livestock, or both. Deciduous trees can provide shade, organic matter, and products within managed farms.
Nutrient resorption : The movement of nutrients from aging plant tissues into tissues that remain alive. Trees reclaim some nitrogen and phosphorus from leaves before shedding them.
Evergreen tree : A tree that retains living foliage year-round, though individual leaves are eventually replaced. It contrasts with trees that shed most or all leaves during a predictable season.
Photoperiodism : A biological response to the length of day and night. Changing day length can help trigger autumn leaf senescence and dormancy.
Temperate forest : A forest biome in temperate regions, generally marked by seasonal changes in temperature and precipitation. Many temperate forests are dominated by trees that lose leaves in autumn.
Silviculture : The cultivation and management of forest trees for ecological or economic objectives. Management practices account for the seasonal growth and leaf fall of deciduous stands.
Carbon sequestration : The capture and storage of carbon, especially in plants, soils, or geological reservoirs. Seasonal foliage affects when a deciduous forest takes up carbon dioxide.
Semi-deciduous forest : A forest where many trees lose leaves seasonally, while others retain some or all foliage. Its mixed leaf-retention patterns differ from forests dominated by fully deciduous trees.
